I called from out of town to set an appointment for the service of papers. My call was answered immediately and followed up with a text giving me all the directions,and information for my request. I emailed the documents over with payment through PayPal (so easy!). Had I not put down the wrong address, the service would have been complete in less than 8 hours from our initial conversation! The next day, first thing in the morning I received a text that the service was complete and my documentation was emailed. So professional!!! I highly recommend Rivera & Associates Private Investigators!!!

Gary has amazing insight. I used to think you only needed a private detective for following or finding someine. Recently we ran into a couple of situations that had us perplexed. They were around a sudden death and the final cal and legal aspects. Gary was amazing. He had great suggestions. Yet; the kindness, understanding and his ability to help defuse the emotions going on were priceless. He is a wealth of information.

    It's a business nightmare. I had a trusted employee whom I suspected of stealing large sums of money over an extended period of time. I didn't know what to do, but I did know who to call. I contacted Stephen Krollpfeiffer and explained the situation. He knew that if I confronted the employee I could be opening a legal can of worms. He instructed me to go about my business as if all was fine. He began his investigation and had soon documented proof of the theft. He even handled the termination. I appreciate that Stephen was very sensitive to my company's needs, and other than a few key individuals, no-one knew anything had happened. I was able to continue to focus on business and, thanks to Krollpfeiffer and Co, we never missed a beat. Now Krollpfeiffer and Co performs background checks on all new hires, so I'll never find myself in the same situation again. If you own a business, you can't afford not to have this same protection.

    I hired Atlas Investigations to assist me with an infidelity issue. I was offered a free consultation where I got to meet the investigator assigned to my case. Frank was able to put a plan together for me that fit my budget, and my needs. I was very pleased with the results and the professionalism of Atlas Investigations! I would recommend them to anyone in need of a private investigator,

    Maghen Ward is absolutely phenomenal. When my husband was cheating on me, I was in such a vulnerable state, she was understanding and reassuring that we wouldn't let him get away with this. Maghen and her team of private investigators get the job done quickly, and exceed every expectation I had. I highly recommend Wards Investigations!

    As a licensed private investigator for over 30 years, I am in constant need of experienced investigators to handle cases from the simple to the complex. I recently was in need of an investigator in the San Francisco Bay Area and Nancy came highly recommended by a fellow investigator. This case involved an international client. Nancy not only worked well with me, but represented my interests with the client equally well. She worked tirelessly on this case both day and night for over two months. I would recommend her without reservation.

    I just came from meeting Steve yesterday. We hired him to place our business and two employees under surveillance. So impressed with his hard work that we hired him to manage all our background checks, penetration testing and investigations in the future.

    Jim did a fantastic job for us on a very sensitive issue. He's very through and meticulous about his work. You will find him resourceful and easy to work with. Hopefully we won't need another private investigator anytime soon but if we did, this is the person we would go with.

    Mike was a well respected supervisor and detective in the Bay Area. I worked with him as he led the investigation into a cold case homicide of a 13 year old girl. Mike was determined and tenacious, and successfully prosecuted the killer in this heinous crime.

    About

    I always hate questions like this because most of my peers are above board ethically and morally. Professionally, I am prohibited from disparaging my peers. What I can say is that when one receives a report from my agency, one knows the information is precise, accurate, and lawfully obtained. I love the vast opportunities and limitless potential for the position. One day an operative may have to knock on a door to interview a witness. In another day, one may have to fly to Beliz, to locate an heir to mansion...

    Q & A

    Answers to commonly asked questions from the experts on Thumbtack.

    What does a private investigator do?

    First and foremost, good private investigators follow laws. Unlike on TV, they don’t break in windows or hack into hospital computer systems to get you intel. When you hire a private investigator, you’re hiring a professional to gather facts and find information for you. Although they can’t obtain certain information (such as health records), they do have access to information that most civilians do not. Often private investigators are hired to perform surveillance or background checks or investigate cases such as adultery, child custody, missing persons, hidden assets, or debugging, and theft or other crimes.

    Private investigators can be hired to interview people and provide that information to the client, perform photo or video surveillance, monitor activity at a location where you suspect criminal activities or questionable behavior, track a person’s movements, find missing people, do deep-dive background checks, and more. Private investigation can be helpful if you’re trying to get a court order but need evidence. Private investigators can also help find birth parents. Nationally, the average price range for private investigation is $70-$210 per hour.

    What does a private investigator cost?

    Private investigation isn’t just for blockbuster action movies. Hiring a private investigator can help in all kinds of situations ranging from finding a birth parent to improving personal security. Nationally, the average price range for private investigation is $70-$210, although pricing often hovers between $40 and $100 depending on the complexity of the services you need. Where you live in the country will affect your costs for private investigation; larger cities have higher business overhead and a higher cost of living, which in turn means higher service rates. The complexity of your case can also affect cost. A basic background check may have a flat rate, while hiring a private investigator to help with your child custody case may require more legwork and research, and therefore cost more. Some private investigators work on retainer. A retainer is essentially a nonrefundable deposit you pay to the professional — meaning you have retained their services — who then works against that amount. Here are some examples of average private investigation costs:

    • Hourly rate: $60-$70; costs can vary based on current fuel prices.
    • Flat rate: $100 for comprehensive background investigation services.
    • Retainer: $1,500 minimum retainer required by some pros before starting work.
    Hire skilled professionals for absolutely everything.
